Michael Kenneth Williams to star in 'Community'

The actor will appear in at least three episodes of the NBC comedy, TV Guide reports.

His character will arrive at Greendale when he takes his first teaching job since leaving prison, where he earned a degree in biology.

Community's creator Dan Harmon teased that Williams's character will be "deeply intense".

"We've had all these crazy teacher characters," he said. "They're so dedicated to their profession that they're kind of nuts or they're off the deep end. So the next logical place to go on that playing field is a deeply intense character. I want to use that as a comedic tool."

Harmon continued: "He's going to be a very dignified guy in a way that has no presentation to it. He studies life and he wants to help other people study it, but he doesn't have any affectation beyond that. He's not trying to prove anything. He's just a very intense person."

Williams previously starred as Omar in The Wire and is currently working on HBO's drama Boardwalk Empire, in which he plays Chalky White.

He has also appeared in shows including Six Degrees, Alias, Law & Order and CSI.
